Experimental measurements of sound attenuation in the frequency range from 0.5 to 10.0 kHz are described. Small plastic bubbles simulating in volume that of an adult anchovy swimbladder were used. Both signal enhancements and attenuations ranging from +5 to −25 dB, respectively, were observed. Effects of bubble location and population density upon the frequency and magnitude of the maximum enhancement or attenuation are described and a simple mathematical model relating these parameters is presented.
